Answer 1

For rectangle

• L=12
• B=4

Perimeter:-

• 2(L+B)
• 2(12+4)
• 2(16)
• 32ft

For semicircle:-

• radius=r=4/2=2ft

Perimeter:-

• πr
• 2π
• 6.28ft

Total:-

• 6.28+32-4
• 38.28-4
• 34.28ft

Answer 2

Answer:

• 34.28 ft

Step-by-step explanation:

Find the length of semicircle

• C = πd, circumference of circle
• C/2 = πd/2 = 3.14*4/2 = 6.28 ft

Find the perimeter

• P = 4 + 6.28 + 2*12 = 34.28 ft
